The Millennium-XXL Project: Simulating the Galaxy Population
simulation We designed the simula-tion project, dubbed Millennium-XXL (MXXL), to follow more than 303 billion particles (67203) in a cosmological box of size 4 2 Gpc across, resolving the cosmic web with an unprecedented combination of volume and resolution While the particle mass of the MXXL is slightly worse than that of the MR,
